lM PROVEMENT lN GANG-FLOWS.

Specification forming part of Letters Patent No. 64,923, dated May 21,1867.

To all whom it may concern:

Be it known that I, JANES W. SURSA, of

useful Improvement in Gang-Blows; and I do hereby declare that thefollowing is a full,

clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure 1 is a side view of my improved gang-plow, with a wheel taken offto show the device for raising and lowering the plow. Fig. 2 is the sameview, showing the device for adjusting the height of the draft-pole whenthe plow is raised or lowered. Fig. 3 is a front-end view.

Similar letters of reference indicate like parts.

This invention relates to an improvement in gang-plows; and consists inthe arrangement of a device for raising and lowering the plows, wherebythey may be set at any required depth for working, or elevated above theground to clear it entirely when the plow is moved from place to place;also, in connection therewith, an arrangement for adjusting thedraft-pole to the plow as it may be raised or lowered. I

A A are plows of ordinary construction, suspended, as usual, to twoplow-beams, B B, which are connected at the rear by a diagonalcross-piece, O, and in the middle, between the wheels D D, by across-tie, E. The plowbeams B B are wider apart at the rear than thefront end, to which the draft-pole F is pivoted, so that the fore endmay be depressed or elevated more or less, as required, to adapt it tothe height of the horses when the plow is raised or lowered, ashereinafter explained. For this purpose an adjusting-screw, a, is set ina bridge, b, on the top of the beams B B, and screws into the rear endof the draft-pole, as shown in Figs. 1, 2. Over the cross-tie E isplaced a transverse shaft, 0, which is hung in iron boxes 0 e at eachend of the cross-tie, and outside of the boxes 0 e segmental arms d dare hung on the ends of the shaft 0. To these segmental arms at d areat'fixed, with screws and nuts, the-axle-arms g g, to carry the wheels DD. The segmentarm d is provided with a number of holes in its peripheryfor receiving the axle-arm g,for the purpose of adjusting the wheel D onthe land-side to the depth required in plowing. The axle-arm g iscomlected with one end of the periphery of the segment-arm d, and at theother end of the segment is pivoted a hand-lever, h, that passes up nearthe drivers seat G, to be operated by him in raising and lowering theplows. The lever h works up and down in'a segmental or curved rack, k.It is provided with a spring on one side to bear against the outsideguide m, and press the lever in the notches of the rack, to hold it fastat any required point of elevation or depression.

It will be seen that when the lever h is raised to the top of the rackk, the segmentarms d d will be raised relatively to the axlearms 9 g,and that the shaft 0 will be actually depressed, thereby lowering theplow-beams BB and the plows A A accordingly, and, when the lever h isdepressed to the bottom of the rack 70, that the operation is reversed,and the plows will be raised above the ground. Their position may alsobe adjusted at any intermediate point of elevation or de pression.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination and arrangement of the shaft 0, the segment=arms d d,the axles g g of the wheels D D, the hand-lever h, and the -rack is, forraising and lowering the gangplows A A, substantially as hereindescribed. 2. The arrangement of the draft-pole F, pivoted to theplow-beams B B, and depressed and elevated by the screw to,substantially as and for the purpose set forth.

The above specification of my invention signed by me this 13th day ofDecember, A.
